Scales for business
Are trade-approved scales with certification necessary or are standard scales without being trade-approved (with certificate?) sufficient for running a home-business where I weigh butters and oils in grams and label my products in grams? Could you recommend a scale which weighs up to 2-5kg? Force-motor scales are quite interesting and generally seem to be more expensive than the strain-gage load cell scales; are they worth the expense if I will be selling creams and balms and possibly perfume in the future (very far future)?
